The adjuster comprises a heat-variable bimetal actuator which is arranged essentially vertically to the bottom of the electrothermal boiling container plane, and the adjuster acts when the water in container is boiling, breaks off more than a group of electrical switching connection points through a trigger mechanism, and cuts off the current of the heating component; as well as a hole which is arranged for the steam to enter into the adjuster, the face or the side under the face is communicated with the hole, and to which a definite distance kept. In this way, when the device is in use, the water which the steam is condensed in the inner surface of the tube can not flow onto the actuator that is arranged vertically, additionally, the water beads which the steam is condensed on the actuator surface will drop to the pot bottom due to the gravity, thereby the more high accuracy of movement of the actuator is ensured.
Description
Technical field
The utility model relates to the controller of electric heating boiling water container, and specifically, when the controller of the utility model design can respond water boiling in the container, the power supply of sever supply container master heater that is to say that what relate to is the boiling water controller.
Background technology
Did to describe in existing widely used boiling water controller such as the International Application No. WO 95/34187.In the disclosed controller of the document, double-level-metal actuator be arranged on a steam pipe lower end below, the upper end of this steam pipe is communicated with internal tank.When the water in the container seethed with excitement, steam pipe was directed to steam on the bimetallic actuator, and when the actuator temperature is raised to when enough high, this actuator action is actuated control lever, and this control lever cuts off one group of electric contact to the power supply of container heating element heater.
But Design of device has a quite serious defective.When the steam in the steam pipe when the inner surface of tube condensation flows on the actuator later on downwards, a particular problem will appear sometimes.Condensed water can accumulate on the actuator, has increased the available heat capacity of actuator owing to stockpiling a large amount of water on the actuator.So both be unfavorable for that the heating actuating also was unfavorable for the heat radiation answer, thereby lost the sensitivity of action that the prolongation actuator required time of operation, the used time of actuator cut-out electric current increased when the water in container seethed with excitement.
Though the CN2423834Y utility model has overcome the one side of above-mentioned defective, but because its heat-sensitive duplex metal actuator is installed on the planar base basic horizontal setting of electric heating boiling water container, water in its container is under the situation of boiling, thereby operation is to disconnect the electric current that one group of electric contact cut off or reduced the supply heating element heater; And a setting is used for making steam to enter the hole of controller, and described actuator is in the described hole of lateral deviation.In such environment for use, because heat-sensitive duplex metal actuator is a horizontal positioned.And actuator is in the described hole of lateral deviation, steam can not flow on the actuator at the water that the inner surface of tube condensation forms, when but the heat steam of high-temperature sprays to the heat-sensitive duplex metal actuator that is in the cold conditions horizontal positioned, still can produce a large amount of globules on the surface that condenses upon actuator, thereby increased the required heat of actuator operation, and then after having prolonged in the container water boiling, actuator action is cut off the used time of electric current.Therefore the CN2423834.Y utility model is a kind of improvement.And can not fundamentally address the above problem.
Summary of the invention
The utility model proposes a kind of new technical solution at the problem that International Application No. WO 95/34187 and CN2423834Y utility model are produced, can overcome the shortcoming of above two kinds of technical schemes fully, reach simple in structure, safe and reliable, willing purpose.
The utility model will solve the problems of the technologies described above the technical scheme that is adopted: a kind of controller of electric heating boiling water container, it is installed on the plane of electric heating boiling water container bottom.It comprises:
A heat-sensitive duplex metal actuator, it is installed in an end of controller housing, in container, move under the situation of water boiling, by an escape mechanism disconnecting the electric contact more than a group, thereby sever supply heating element heater power supply; It is characterized in that described jet chimney hole, aim at the bottom of the basic vertical kettle or have the center or the center downside of the heat-sensitive duplex metal actuator that constant slope is provided with.So in use, steam is once enter in the vapor chamber, because bimetallic actuator is vertical placement.Both made the heat-sensitive duplex metal actuator surface cohesion globule, also can be owing to the gravity effect of the globule, the globule can flow to the vessel bottom immediately.And be focused at possibility on the heat-sensitive duplex metal actuator from eliminated condensed water at all.Simultaneously, be that front or front downside (steam is upwards) spray also just because of steam hole and bimetallic, also avoid the CN2423834Y side direction to depart from the diffraction in hole fully, thereby fundamentally accelerated the response time of steam cock behind the boiling water.
At the bottom of the described basic vertical kettle or exist the heat-sensitive duplex metal actuator of constant slope setting also can described steam hole be set at the downside that departs from the centre fully or the following left and right sides, because vapours moves upward, it can make the heat-sensitive duplex metal actuator action fully.
Described controller is characterized in that, described heat-sensitive duplex metal actuator is the bimetallic actuator of a constant temperature quick-action, preferably the quick-action constant temperature bimetallic actuator of known type in the prior art.
Described controller is characterized in that, the bimetallic actuator position is installed has one to mould the system vapor chamber.With heat of aggregation steam, shorten the response time of heat-sensitive duplex metal actuator.
Described controller is characterized in that, comprises a pipeline or a semicircular that is directed to certain distance below the heat-sensitive duplex metal actuator center of circle or the center of circle, to guarantee the vectored injection of vapours.
Described controller is characterized in that, the upper end in described hole has a circulus setting to be used for the end of coordinating with steam rapid heat cycle pipe to connect.
Fitting surface can tilt, for example to be suitable for the tapering point of fixed steam pipe.But for simplicity for convenience, fitting surface is preferably substantially parallel with pipeline.
Should be appreciated that the utility model and CN2423834Y utility model working condition have very big difference, be to guide steam into heat-sensitive actuating device that basic horizontal is provided with in the prior art always.It is believed that in the past move institute's time spent minimizes with regard to the boiling that is enough to make water in the heat-sensitive actuating device response container.Yet find again, can obtain enough heats of operate actuator from the steam of sideways diffusion, but the water of collecting on the actuator is too many, or because the mode that diffraction penetrates still can affect the speed of response.Especially in the steam complications around can be bigger to time infringement.
In the use of reality, also can be according to the difference of environmental condition, the device tracheae is positioned at actuator center lower position, when feed channel was sprayed at the center downside, because heat steam moves upward, heat steam can be tied and gather in steam cavity at once like this, cause the steam cavity temperature to improve rapidly, and heating causes the heat-sensitive duplex metal actuator action, backs down electric switch by escape mechanism, thereby cuts off the electricity supply.
Because of the reason of the limitation of environment for use, also steam pipeline can be placed two sides about the below of bimetallic actuator of vertical placement.Because heat steam is the cause that moves upward, also can reach same purpose.
About the work of bimetallic actuator, it also needs one to be convenient to circulate and tie poly-steam cavity.Its knot that should as far as possible guarantee steam when action is poly-, and after action, then should discharge by as soon as possible that knot is poly-steam.Make when moving can be sensitive more next time.
